4Claims. (01.155-195) The present invention relatesto chair structuresand more particularly to supporting pedestals for chairs of the typeinstalled in motorbusses or other vehicles.

The primary object of the invention is to provide a unitary sheet-metalpedestal for supporting the frame of a chair structure in which thechair seat and chair back are mounted on said frame.

This and any other and more specific objects hereinafter appearing areattained by, and the invention finds preferable embodiment in, the chairstructure hereinafter particularly described and illustrated by theaccompanying drawing, wherein:

Figure 1 is a perspective view of a chair structure of the type commonlyinstalled in intracity transit motorbusses, supported on a pair ofpedestals constructed according to the present invention;

Figure 2 is a fragmentary view of the same shown partly in sideelevation and partly in longitudinal, central vertical section throughone of the supporting pedestals;

Figure 3 is a horizontal sectional view taken on line 3--3 of Figure 2;and

Figure 4 is a plan view of a unitary sheet metal blank from which thesupporting pedestal is fabricated.

Referring now in detail to these drawings wherein like parts aredesignated by the same numerals in the several views, the chairstructure there shown comprises a conventional, up holstered chair seatI0 and chair back I I mounted in conventional manner on a, tubular metalsupporting frame I2 having substantially horizontal and parallel tubularfront and rear cross bars designated I3 and I 4 respectively upon whichrest the chair seat Ill.

The frame I2 of the chair structure is supported by a pair of spacedpedestals generally designated I5 and each fabricated in accordance withthe invention from a unitary sheet-metal blank as shown per se in Figure4. This blank is bent to form an upright tubular member having parallel,vertical side walls I6 connected by a semi-cylindrical front wall I1,the rearward ends of the metal sheet being turned inwardly as at I8 andbutt-welded together to form a semi-cylindrical rear wall. The upperedges of the side walls II; of the pedestal slope rearwardly-downwardlyand are slightly crimped as at I9 and 20 to form seats in which rest thefront cross-bar l 3 and rear cross-bar I4, respectively, of the chairframe.

The front wall I! of each pedestal has an extension 2I onits upper endwhich is curled rearwardlyover and around the tubular front crossbar I3of the chair frame and welded thereto, and the rear wall of eachpedestal has similar extensions 22 which are curled forwardly over andaround the tubular rear cross-bar I4 of the chair frame and weldedthereto.

The lower ends of the side walls l6 of each pedestal are flangedoutwardly to form feet 23 which are provided with apertures 24 thereinfor the reception of bolts 25 by means of which the pedestal may besecured to the floor of a vehicle.

It will thus be seen that the present invention provides a unitarysupporting pedestal for a chair structure, which pedestal is simply andeconomically constructed, efficient in its intended function andattractive in appearance, and while but one specific embodiment of theinvention has been herein shown and described it will be understood thatmany details thereof may be altered or omitted without departing fromthe spirit of the invention as defined by the following claims.

I claim:

1. In combination with a chair structure having a seat-supporting framecomprising substantially horizontal and parallel front and rearcross-bars, a supporting pedestal for said frame comprising an uprighttubular member having spaced vertical side Walls supporting on theirupper forwaird edges said front cross-bar at spaced points thereon andsupporting on their upper forward edges said front cross-bar at spacedpoints thereon, said tubular member having an extension on the upper endof its front wall curled over the top of the front cross-bar and securedthereto and an extension on the upper end of its rear Wall curled overthe top of the rear cross-bar and secured thereto.

2. In combination with a chair structure having a seat-supporting framecomprising substantially horizontal and parallel front and rearcross-bars, a supporting pedestal for said frame comprising an uprighttubular member having spaced vertical side walls supporting on theirupper forward edges said front cross-bar at spaced points thereon andsupporting on their upper rearward edges said rear cross-bar at spacedpoints thereon, said tubular member having an extension on the upper endof its front wall curled over the top of the front cross-bar and securedthereto and an extension on the upper end of its rear wall curled overthe top of the rear cross-bar and secured thereto, and said tubularmember having feet extending outwardly 3 a from the lower ends of itsopposite side walls and adapted for attachment to a supporting floor.

3. In combination with a chair structure having a, seat-supporting framecomprising substantially horizontal and parallel front and rearcrossbars, a supporting pedestal for said frame comprising a unitarysheet of metal bent to form an upright tubular member having spacedvertical side walls supporting on their upper forward edges said frontcross-bar at spaced points thereon and supporting on their upperrearward edges said rear cross-bar at spaced points thereon and aconnecting front wall, and having its rearward ends turned inwardlyand'butt-welded'together to form a rear wall, said tubular member havingan integral extension on the upper end of its front wall curled over thetop of the front cross-bar and secured thereto and an integral extensionon the upper end of its rear wall curled over the top of the rearcross-bar and secured thereto.

4. In combination with a chair structure having a seat-supporting framecomprising substan-' tially horizontal and parallel front and rearcross-bars, a supportingpedestal forsaid frame comprising a unitarysheet of metal bent to form an upright tubular member having spaced.vertibar and secured thereto and an integral extension on the upper endof its rear wall curled over the top of the rear cross-bar and securedthereto, and said tubular member having feet flanged outwardly from thelower ends of its side walls and adapted for attachment to a supportingfloor.
